To all wlw/mt 'may concer/it Be it known that l, JOHN Seri-UniA Benoit, a subject ot the Kingdom ot Great Britain, residing at `Havelock l/Vorlis, Holloway l-lead, Birmingham, in the county ot Vilarwick, England, have invented and useful improvements in or Relating to Fasteners ior Hinged Doors or `illindows, Such as the Doors ci Show Cases and the like, of which the following is a specilication. i

rllhis invention comprises certain improvements in or relating to fasteners tor hinged doors, or windows, such as thedoors of show `cases and the like, and refers to the type ot fastener involving a vertical or longitudinal rotary member,r which by rotation is adapted to retain the door or window inthe closed condition, and `to partially open or completely close the door by its action.

According' to the present invention the said vertical or longitudinal rotary member isadapted to be actuated by or from a rotary member located at right angles thereto. This member may pass through `the woodwork ot the door or window so that the rotary member may be located on the rear side thereof.

ln cases in which two doors or windows are adapted to close towards each other, the present invention may be adapted to retain both of said doors or windows, and the present invention may furthermore be oi' a char eter such that in the opening irocess one ot the doors is initially displaco while at the same time the other door 1s maintained in its closed condition during said initial displacement, thereby ensuring that the one door is treed from the other prior to the opening of the latter.

In order that this invention may be clearly understood and readily carried into practice, reference may be had to the appended explanatory sheet ot' drawings, upon which :M

Figure 1 is a fragmentary elevation ot a door fastener in the closed position constructed in accordance with one form of the present invention.

Figure 2 is a section taken on line a fr of Figure l.

Figure 3 is a fragmentary elevation illuscertain new ti-ating the fastener in .an intermediate on midway rposition in the operation oi fastening or unt-listening the door or the like,

Figure 5 is a iu'rth'er fragmentary elevation illustrating the 'fastener in the released or` untastened position the door or doors befree to open. n f `Figure 6 is a section taken on line e .e of Figure 5, and,

Figure is a :fragmentary side or edge elevation ot the `fastener shown in Figure `5 looking inthe direction ot thearrow (t.

ln a convenient `embodiment et the presn ent invention, the horizontalrotary meinber l which may outwardly have a suitable handle 2 or :lever or key journalled in the door or frame 2 is inwardly furnished with an arm 3 adapted to oscillate the vertical rotary member et. Said rotary member l comprises a pair of alined rods a? which are spaced apart, and a yoke d which connects their opposing ends. y The arm 3 be bifurcated as shown in Figure 7, and passing through and bridging the biturcations a barrel or rod 8 is provided, the axis of which is parallel with the handle spindle i which barrel or rod 8 is adapted to rotate and slide axially in relation to the bifurcations on the arm 3. Passing at right angles through the said barrel S and capable ot a sliding movement in relation thereto is rod 9. This rod 9 is parallel with and eccentric to the rods da and carried by the yoke lb ot the rotary member il., The connection between the haiidle spindle i and the vertical rotary meml thus involves tour rotary axes and two sliding connections. The invention is not. however, in any wise restricted to the mechanism tortransmitting the movement ot the l'ioriaontal rotary member l to the vertical rotary member 4, Ls this may oe modified considerably,

The vertical member has an attached or integral crank part or parts l0 adapted to -tahe behind the adjacent door or trame 11a.

There may be a part l0 at each extremity oit the rotary member and a part at any other desired position therein, while the said part or parts l0 may extend throughout the entire length of the rotary member. The said part at each extremity of the rotary member may comprise an arm as illustrated having a rounded extremity 11 and adapted to co-operate with larear surface;l2ap pertaining 'to the adjacent door ATor" frame lla Figures 2, 4 and 6 and also with an integral projection or lug 13.*on the` adjacent door or frame 11a which projection or'lug extends to the rearof the saidarm` 1Q so that when the vertical member 4 is rotated to open the door 2a the latter is forced open by co-operation of the l0 `With 'thep'rm jection 13 to the rear of the same, When this projection 13 is ony t-headjacent door il as illustrated the effect of this is that 'said' adjacent door lla is retained closed during the initial movement of the door Qa'by which the fastener is carried, particularly "illustrated in Figures 2, l and 6. In these 'circumstances two of the projections maybe provided7 one 13 being mounted upon Ithe Vadjacent door l1a and the other l5 pon the framework lll. Both Vof these Aprojections 13 and l5 may cao-operate With one 'and the samearm l0 upon the rotary member 4 so that by virtue of the projection 15 which is on-the frame lll ,the door Qa'carrying the fastener is forced open, While by virtue of the projection 13 Which is upon the adjacent door la the latter is retained close .l

lVlien there is only" one hinged door say 2 and the part lli" is in the nature of a" permanent or `fixed part secured tofthe `rframe la either of the projections or lugs 13 or l5A may be dispensed With.

` rodarranged at -"rigl`1t.jangles to and What I claim as my invention, and desire to secure by Letters Patent is 1. A hinged door or Window fastener comprising a hook-shaped keeper forapplication to a frame` orthe like,-a rotary member for application to a door "or vvindovvy and having a crank member for engagement Witlrfhsaid hook-shaped keeper, said rotary member alsoliaving a'l'r'd parallel With and eccentric tod `its axis, 4a `manually `operable rotary-member having a crank arm provided With a slidably and revolubly mounted slidably engaged With the first named rod.

2. A hinged door'oi` Window fastener comprising' :ibook-shaped keeperfor fapplication'to'aframe or the like", a rotary member for Tapplicatien" to a door l or Windovvand lhaving a "crank member for engagement with said "liooklsh'apedkeeperfsaid rotary member also having afyoke, arod insaid yoke parallel with and extending to` the axis of saidineber, a manually `operablerotary meinber'lratfing afcra'nkarmA prdvided with a slidably and revolubly mounted rod arranged at right angles 'to and "slidabl'yengaged lWith the jrst named rod.
